Can rats eat yogurt?
Quick Answer
Yes
Rats can eat yogurt in moderation. It is a good source of protein and calcium for them. However, too much can lead to digestive issues due to the lactose content.

What Is It?
Yogurt is a food produced by bacterial fermentation of milk. The bacteria used to make yogurt are known as yogurt cultures, which ferment lactose, the sugar in milk. This process produces lactic acid, which acts on milk protein to give yogurt its texture and tart flavor.
Why It Can Be Risky
While yogurt can be beneficial for rats, there are some risks associated with feeding them too much of it.
- Yogurt contains lactose, and while rats can tolerate small amounts, too much can cause digestive issues.
- High-fat yogurts can contribute to obesity in rats.
- Some yogurts contain added sugars, which are not good for rats.
Safe Method?
It’s best to feed your rat plain, unsweetened yogurt and only in small amounts. A teaspoon per week is a good measure.
Safe Alternatives
If you’re looking for other healthy treats to give your rat, consider fruits like apples and bananas, or vegetables like broccoli and carrots. Always introduce new foods gradually and in small amounts.
